Elias Canetti on Kafka's Letters To Felice

"To call these letters a document would be saying too little, unless one were to apply the same title to the life-testimonies of Pascal, Kierkegaard, and Dostoyevsky. For my part, I can only say that these letters have penetrated me like an actual life, and that they are now so enigmatic and familiar to me that it seems they have been mental possessions of mine from the moment when I first began to accomodate human beings entirely in my mind, in order to arrive, time and again, at a fresh understanding of them."
